Title: Improvements relating to variable area jet nozzles of turbojet engines
Inventor: EGBERT WILLIAM FREDERICK
IPC: F02K1/12
Filed: 1959-03-16
Abstract: 850,508. Jet propulsion nozzles. GENERAL MOTORS CORPORATION. March 16, 1959, No. 9107/59. Class 110 (3). A gas turbine jet propulsion engine has an exhaust duct terminating in a variable area nozzle comprising overlapping flaps pivoted to the exhaust duct, a shroud duct surrounding the exhaust duct and terminating in a variable area shroud nozzle comprising overlapping flaps pivoted to the shroud duct, the shroud duct being axially movable and connected to the flaps of the jet nozzle so as to move them about their pivots, the jet nozzle flaps being.connected to the shroud nozzle flaps so as to move the latter also. The high-velocity high-temperature exhaust gases from a gas turbine jetpropulsion engine are discharged from the reheat combustion chamber casing 26 through a variable area nozzle formed by overlapping flaps 46 pivoted to the casing 26 at 48. Each flap 46 has an actuating plate 50 containing a cam slot 52. An annular chamber 34 is formed between an annular shroud duct 36 and the casing 26 and is supplied with air passed from the engine intake through a space formed between the engine and its nacelle. The shroud duct 36 has a variable area shroud nozzle 38 formed by overlapping flaps 62 pivoted to the duct 36 at 64. The shroud duct is axially slidable with respect to the casing 26 by means of a number of actuating cylinders. A conical member 54, provided with air passages 56 and a number of U-shaped brackets 58, is secured to the shroud 36. Each bracket 58 carries a pin 60 which co-operates with a cam-slot 52 so that axial movement of the shroud 36 rotates the flaps 46 about their hinge axes 48. Each flap 62 has an actuating-plate 66 formed with a cam-slot 68 which co-operates with a cross-pin 72 carried by an arm 70 attached to each jet nozzle flap 46 so that movement of the shroud will also vary the outlet area of the shroud nozzle. The cam slots 52, 68 are shaped so as to vary the ratio of the outlet areas of the exhaust and shroud nozzles and the ratio of the axial distance between the boundary edges of the nozzle outlets to the square root of the outlet area of the exhaust nozzle. In the arrangement shown these ratios are maintained constant,

Title: Improvements in or relating to absorption refrigerating apparatus of the inert gas type
IPC: F25B15/10
Filed: 1952-04-18
Abstract: 706,533. Refrigerating. ELECTROLUX, Ltd. April 18, 1952 [April 26, 1951; April 3, 1952], No. 9774/52. Class 29 Refrigerant withdrawn from the normal circulation in continuous cycle inert gas absorption apparatus is accumulated in a vessel 26 with a liquid space in communication with a vessel containing absorption solution e.g. the absorber vessel 27, and is returned bodily into circulation by utilising variations in the distribution of absorption solution caused by external control means e.g. the usual thermostat regulating the heat supply to the boiler system ofa manual control. As shown the absorber vessel 18 is divided by a partition 24, having an opening 28 in its upper part, into the absorber vessel 27 and the accumulator vessel 26 to which unevaporated refrigerant from the evaporator 15 is supplied through the inert gas pipe 19. A pipe 30 opening above the .base of the vessel 26 is connected to the rich liquor pipe 22 to form the liquid connection between the two vessels. During normal operation tne concentration of refrigerant in the two chambers 26, 27 is substantially equal. Upon rise of temperature of the air cooling the condenser 14 and absorber 17 evaporation in the evaporator 15 will be incomplete and the surplus liquid refrigerant flows from the evaporator through the gas heat exchanger 16 and pipe 19 to the vessel 26, decreasing the specific gravity of the absorption solution therein so that the liquid level will stand somewhat higher than that in the vessel 27. Operation then continues with the weaker solution causing complete evaporation. If the air temperature now falls the temperature of the evaporator falls, the thermostat switches off the heat supply to the boiler 10 and the action of the pump 12 ceases or is reduced. The liquid column in the boiler between the levels I and II together with the solution contained in the absorber coil continues to flow into the absorber vessel 27 raising the lever therein. Since the level in vessel 26 is higher than that in vessel 27 it will reach the opening 28 earlier and high concentration liquid will flow into the absorber vessel 27 returning some of the withdrawn refrigerant to the circuit. The mean concentration of the liquid in the accumulation vessel 26 is closed such that several operations of the thermostat are necessary before equalization of the concentration in the vessels 26, 27: The pipe 30 may be replaced by a small opening in the lower part of the partition 24. A small opening may be provided in the pipe 30 immediately above the base of the accumulation vessel; and the pipe 19 may open beneath the liquid level to improve the mixing and have an opening in its side to allow gas flow through the absorber vessel. Specification 319,015, [Class 29], is referred to.

Title: An emergency appliance for producing potable water from sea water by distillation
IPC: C02F1/18
Filed: 1962-03-14
Abstract: 958,708. Portable stills for distilling sea-water. G. INGRAM. Dec. 6, 1962 [March 14, 1962], No. 9794/62. Heading B1B. In a portable still for obtaining potable water by the distillation of sea water, the heat generated by the human body is used to vaporize water from a sponge saturated with sea water. The still comprises a waterproof envelope 1 divided into upper and lower compartments 2 and 3 respectively by an inclined waterproof partition 4, and is of a size and shape whereby it may be worn on the human body in the manner of a breast plate with the upper compartment 2 directed upwards towards the chin. Compartment 3 contains a sponge 8, which is saturated with sea water. The body heat of the wearer causes the vaporization of water from the sponge and the vapours formed pass into compartment 2 via an opening 11 in partition 4. The vapour condenses as droplets of water on the walls of compartment 2, and these droplets collect in the area 6 of the envelope, from whence the potable water can be sucked by the wearer through the flexible outlet tubes 13. The envelope is preferably made from a suitable flexible plastics material, either stout enough to maintain its opposed walls apart when worn or else provided internally with ribbed spacing elements of plastics material (not shown) to keep the opposed walls apart, and is provided with a neck strap 7. The sponge 8 may be removed from compartment 3 for soaking in sea water via an opening in the envelope normally closed by a sliding clasp 10.

Abstract: 967,531. Automatic voltage control. TELEFUNKEN PATENTVERWERTUNGS G.m.b.H. March 13, 1963 [March 15, 1962], No. 9878/63. Addition to 957, 548. Heading G3R. The voltage regulator described in the parent Specification is provided with a modified overcurrent protection circuit. As shown, when the regulator is used with a capacitor 13 connected across output terminals I, II this capacitor would act as a short-circuit when the regulator was initially switched on, because of its charging current, and cause the protective circuit including transistor 2 to operate, whereby no output would result. However, the provision of a capacitor 14 connected as illustrated causes the voltage at the base of transistor 2 to rise more slowly than the voltage across the output terminals; the protection circuit thus becomes fully effective only when the capacitor 13 is fully charged and premature operation is prevented. A thermistor or an inductor; connected in place of resistor 1, may replace the capacitor 14, or the three elements may be used in any combination.
